The Lowdown
Well, folks, let’s talk about the next couple of weeks. The short version: we’ve got a solid, drawn-out run of surf at Lakey Pipe, with a couple of definite standouts if you time it right. There’s no real gap at the start—the waves are already here and they’re hanging around for a while.
We kick things off on Wednesday the 12th with a clean, cross-off breeze and a solid 6ft of SSW swell pushing through. The energy is already pumping at 2272, so it’s not just background noise. This is real, rideable swell, and with that light, offshore touch, the lineup should be clean and organized. It’s a bit meaty for beginners, mind you—over 5ft—so this is for the intermediate crew who know their way around a reef.
That pattern holds through Thursday and Friday, but I’m keeping an eye on Thursday the 13th. The swell bumps up a touch to 7ft in the afternoon, but more importantly, the period jumps to 16–17 seconds. That’s proper groundswell, the kind that puts some real punch in the wave. It’s a touch more critical on the reef, but for experienced surfers, this is where it starts to get fun. The energy reads 2136 in the afternoon, so there’s plenty behind it.
The weekend rolls in with more of the same—Saturday the 15th and Sunday the 16th keep that 6ft to 7ft SSW swell rolling, with light, clean winds. Crowds are a real possibility at this break, so if you want a quieter peak, paddle out early. The consistency is there, and it’s all quality surf.
Now, here’s where I get a bit excited. From the 18th through the 22nd, things start to build. We see the swell creep up into the 8ft to 8ft range, and the energy numbers jump into the 3000s and even 3700s. This is serious swell. For the average punter, it’s going to be a lot of water moving over that reef, so I’d call this an experts-only window. The 19th looks particularly strong, with a morning swell of 8ft at a long 18 seconds and energy at 3535. That’s a proper groundswell event. Just remember, long-period swells like this can be a bit tricky on a reef—they throw a lot of water around, and the sets can be big and shifty. But for the crew who can handle it, this is the best of the lot.
The 20th has a bit of a question mark on it with a marginal tide morning, but the afternoon on the 20th and all of the 21st look spot-on. The 21st is another standout—clean, 8ft at 17 seconds, energy at 3763. That’s a big, powerful day. But honestly, from the 19th through the 24th, we’re in the thick of it. The 23rd sees a massive jump in period to a very long 23 seconds in the morning with 3115 energy, and the afternoon is even beefier with 4690 energy at 20 seconds. That’s a lot of water moving. That kind of period is best handled at a reef like this, as a beach break would just close out. But at Lakey Pipe, it’s going to be a freight train.
After that, we start to wind down. The 25th and 26th still have solid 6ft surf, but the energy drops off. By the 27th, we’re down to 4ft with 601 energy—still clean, but it’s a definite step down. If you want the big stuff, mark your calendar for the 20th and 21st. That’s the prime window. The long-range stuff later in the month is promising, but as always, the closer we get, the more we’ll know.
Alright, keep your eyes on the horizon and your wax on. This is gonna be a good run.

Information about the Lakey Pipe Surf forecast
The above surf forecast table for Lakey Pipe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lakey Pipe can be found by selecting the local surf guide option on the grey menu. Our Lakey Pipe surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Lakey Pipe) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Lakey Pipe may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
